Here are some events Wednesday celebrating Earth Day:
Anne Arundel County
St. John's College: Students will demonstrate rain barrel installation, 3 p.m. to 4:30 p.m., at two sites on the campus in Annapolis. Pinkney Hall, on the east side of campus, facing McDowell Hall, and the Carroll Barrister House, an administrative building on Prince George Street. Once they are attached to existing downspouts, the barrels catch and reduce the first onslaught of storm water from roofs. The water then seeps through attached hoses to water surrounding plants and shrubbery, which filter out pollutants. The demonstrations are free and open to the public.
FOR THE RECORD - A photo caption in Wednesday's editions misidentified the park where Baltimore County Executive James T. Smith Jr. appeared for an effort to prevent trash from being dumped into storm drains. He was at Stansbury Park in Dundalk. The Baltimore Sun regrets the errors.
Community College of Baltimore County: Activities are scheduled throughout the day at the three campuses. Events include a Green Fair Expo from 11 a.m. to 1 p.m. in Catonsville, sustainability videos from 10 a.m. to noon at Dundalk and composting from 1 p.m. to 2 p.m. at Essex.
Patapsco Valley State Park, Hilton Nature Center, Halethorpe, will offer various activities from 3 p.m. to 6 p.m. Park staff, the Maryland Conservation Corps and Maryland Park Service officials will participate.
Harford Community College, 401 Thomas Run Road, Bel Air, will mark the day from 11 a.m. to 2 p.m. with world music, dancing, a movie and free vegetarian lunch. There will also be a poster contest.
